GEORGE A. WALSH AND LOUIS B. LA VIGNE, OF EAST TOLEDO, OHIO.

WATER-SEPARATING APPARATUS.

To all whom. t may Gomera United States, residing at East Toledo, in the county of Lucas and State of Ohio,

have invented certain new and useful 1m tion is to provide a device which may be in-` serted as the rear wall of the furnace, and which will form a water heating and purifying device.

Another object of the invention is to provide the attachment with a filter which will separate the dirt from the water entering the attachment and prevent it from being carried into the boiler.

Another object of the invention is to provide an attachment which is so constructed that the dirt may be easily washed out when necessary.

lWith these and other objects in View this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

ln the accompanying drawings Figure 1 is a view showing the furnace in side elevation. Fig. 2 is a top plan view of the furnace. Fig. 3 is a vertical longitudinal sectional view through the attachment. Fig. 4 is a vertical sectional view through the attachment taken along the line 3 3, in Fig. 3. Fig. 5 is a sectional view through the attachment taken along the line 5-5, in Fig. 8. Fig. 6 is an elevation of the attachment. Fig. 7 is a perspective view of the filter.y Fig. 8 is a transverse sectional view through the filter along the line 8-8, in Fig. 3. Fig. 9 is a perspective of one of the plates forming part of the filter. Fig. 10 is a perspective view of one of the plates which forms the side walls of the attachment. Fig. 11 is a perspective view of the coupling at the base of the attachment.

This invention comprises a furnace having its boiler 10 supported by a briclr base 11, which base has its rear wall removed and replaced with the attachment forming the subject-matter of this invention. This attachment comprises a hollow casing formed from the plates 12 each of which is Specification of Letters Patent.

provided with the curved ends 13 and 14.

The curved end portion 14`has its edge portion 15 olf-set to Aform a pocket in which the end portion 13 of thesecond plate 12 lits as shown in Fig. 5. `V-'shaped tongues 16 eX- tend from the plates 12 and are connected by the end plates 17, which end plates are provided with flanges 18 extending around the lower portions of the plates 12 between the tongues 16. Rivets 19 are passed through the plates to secure the saine together and stay rods 20 extend transversely through the casing with their end portions extending through the openings 21 formed in the 'plates 12. Plugs 22 are screwed into the openings formed in the plates 12 to permit a hose to be passed into the casing and the interior of the casing cleaned.

The cover 23 fits within the walls of the casing and is secured inplace by the rivet 24. A man-hole 25 is formed in the center of the cover 23 and is surrounded by a -plate 26 which overhangs the opening 25 and car- A closure plate for the 29 which passes through an opening formed in the bridge 27 and has its upper end threaded so that a securing nut 30 may be placed upon the bolt to hold the closure in a locked position.l A draw-off pipe 31 leads from the `upper portion of the casing through the cover and extends to the forward portion of the boiler 10. This pipe 31 is provided with a control valve 32 which may be openedand closed to control the feeding of water to the boiler and is provided near itsy forward end with a check valve 33 which prevents the water from fiowing through the pipe 31 from the boiler to the attachment, but permits the water to 'How freely from the attachment into the boiler.v The bottom portion of this casing is tapered as shown in the drawings to form a sort of hopper in which the caked mud is intended to collect. An opening 34 is formed in the center of the tapered bottom and communicates with a threaded pipe 35 having a funnel shape upper portion 36 which lits about the lower portion of the hopper and is secured in place by the rivets 37. A valve 38 is screwed upon the threaded portion of the pipe 35 so that the flow of water through the pipe 35 may be controlled. A drum 39 passes through the casing just above the hopper and communicates with the interior of the furnace beneath the boiler so that the interior of the furnace may be cleaned when necessary. This drum has its outerA end closed by a door 40 which door is normally held closed by the latch 41.

An inlet pipe 42 extends into the lower portion of the casing above the drum 39 and is provided with a vertically extending inner end portion 43 extending into the housing 44 forming the housing of a filter. This filter is provided with a number of diagonally extending perforated plates 45 constituting screens to collect the ine dirt in the water and form it into cakes of solid mud. The water which passes through the inlet pipe passes into the upper portion of the housing 44 and then flows downwardly through the screens 45, which screens remove the fine dirt from the water. The waterl which enters the casing will, therefore, be practically clear and, therefore, the water which is fed into the boiler through the pipe 3l will contain no foreign matter which will be liable to coat the inner face of the boiler. The mud which gathers in the filter will gradually work down through the plates until it reaches the lower end of the housing 44 and from here it will drop down. into the hopper where it can be easily flushed out by opening the valve 38.

A check valve 46 is provided inthe inlet pipe 42 which valve will permit the water to flow into the casing, but will prevent the waterl in the casing from flowing back through the valve. The water flowing through the pipe 42 may be supplied from the city water main or may be forced through the pipe by a suitable pump.

When it is desired to clean the casing the water is removed from the casing through the valve 38 and the closure 28 is then removed to permit a person to crawl through this man-hole opening and into the interior of the casing. The plugs 22 are then removed and a hose passed into the boiler so that the man cleaning the boiler can squirt water against the sides of the plate l2 and remove any dirt` from the plates which may have gathered upon them. After the casing has been cleaned the closure is replaced and the valve 38 closed. Water is then fed into Eboiler. This will prevent the temperature of the water in the boiler from being lowered when it is necessary to feed water into the boiler.

Having thus described the invention what is claimed as new, is

l. In a,v furnace, a support, a boiler carriedV by said support, a water reservoir forming a portion of one of the walls of said support, a. drum passing through said reservoir for permitting access to the interior of said support beneath said boiler, a pipe leading from said reservoir to said boiler, and a feed pipe communicating with said reservoir.

2. A boiler attachment comprising a casing formed from a plurality of plates having their edge portions secured together, the tapered face extending from the lower portions of said plates, plates connecting said tongues to form a hopper in the lower portion of said casing, a drum extending through said casing above said hopper, an outlet leading from said hopper, an inlet pipe entering said casing above said drum and provided with a vertical inner end portion, a housing inclosing the inner end portionofsaid inlet pipe and provided with an open lower end portion, screens mounted in said housing` for collecting foreign matter in water passing through said inlet pipe and dropping the same into said hopper, and a draw-off pipe leading from said casing.

In testimony whereof we hereunto aliiX our signatures in presence ofV two witnesses.
